This would be John Manton & Sons of Dover Street, London. the company operated for many years through the 1840's, 50's, 60's. John Manton was one of the few gunmakers stamping bore sizes before they were required (Greener and Reilly being two others). He signed the famous open letter in the field in March 1858 supporting the reopening of the Military trials in favor of the Prince Patent breech loader.

John was Joseph's brother. He died in 1834. The firm must have afterwards been run by his sons. IGC will have the history but I do not frequent that site after certain unpleasantness. Lagopus will know. We had a line discussing Manton & Co. in Calcutta once. (Lots of bad info available on the internet I understand).
